Quick answer: the most common mistake is never recording a new deed into the trust's name for real estate. The most common Wyoming-specific mistake is forming an LLC to hold real property but never transferring its membership interests into the trust.

Signing ≠ funding
1. Real estate deed never recorded — the #1 mistake
Moving real estate into a trust requires a new deed, signed and recorded, naming the trust as owner. This is the step most often skipped. Left undone, that property remains a probate asset — subject to the full District Court process, regardless of the trust document sitting in a drawer.
2. LLC formed, but membership interests never assigned — Wyoming's own risk
The Wyoming LLC-and-trust workaround for the real-property perpetuities limit only works if both steps happen: the real estate goes into the LLC, and the LLC's membership interests go into the trust. Families sometimes complete the first step and stop, leaving the trust holding nothing and the real property's long-term duration benefit unrealized.
3. Financial accounts left titled individually
Bank and brokerage accounts don't join a trust automatically. Each one has to be retitled into the trust's name, or the institution needs a copy of the trust document plus a change-of-ownership form. Accounts opened after the trust was created are especially easy to forget.
4. Treating the small estate affidavit as a safety net
Wyoming's small estate affidavit and summary distribution — up to $400,000 — is a genuine shortcut for modest, unfunded assets within that threshold. It's not a backstop for a house, a business interest, or a larger account left outside the trust by mistake; those amounts require full probate.
